The CNG supply rate was defined as the heat energy ratio of the supplied CNG to the total heat energy available in the cylinder. The results showed that the brake thermal efficiency was similar to that of ordinary diesel operation at BMEP=0.67MPa even when the CNG supply rate was raised to 74%. When the CNG supply rate was higher than 75% ignition became very unstable and the brake thermal efficiency decreased significantly as well as the HC emissions increased sharply. The reason for this is considered to be that the appearance of miss fire cycles gave rise to combustion fluctuations. To reduce NOx emissions, the effects of intake air dilution with nitrogen gas were also investigated.","subitem_description_type":"Abstract"}]},"item_2_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"新潟工科大学"}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1342-792X","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10590360","subitem_source_identifier_type":"NCID"}]},"item_2_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉本, 康文"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大村, 卓稔"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-02-25"}],"displaytype":"detail","filename":"15_1-8.pdf","filesize":[{"value":"384.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"15_1-8.pdf","url":"https://niit.repo.nii.ac.jp/record/195/files/15_1-8.pdf"},"version_id":"ba868474-f6ef-40f2-9ccd-c291ae440201"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Diesel Engine"},{"subitem_subject":"Alternative Energy"},{"subitem_subject":"Dual Fuel"},{"subitem_subject":"Natural Gas"},{"subitem_subject":"Engine Performance"},{"subitem_subject":"Exhaust Emissions"},{"subitem_subject":"NOx Reduction"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"天然ガスを吸入する二元燃料ディーゼル機関の燃焼特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"天然ガスを吸入する二元燃料ディーゼル機関の燃焼特性","subitem_title_language":"ja"},{"subitem_title":"Combustion Characteristics of a Dual Fuel Diesel Engine with Natural Gas as the Main Fuel","subitem_title_language":"en"}]},"item_type_id":"2","owner":"4","path":["22"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-03-02"},"publish_date":"2011-03-02","publish_status":"0","recid":"195","relation_version_is_last":true,"title":["天然ガスを吸入する二元燃料ディーゼル機関の燃焼特性"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2023-06-20T05:49:27.862879+00:00"}
